When I decided to install some new movable equipment in my industrial unit, I set about designing a trolly which could accommodate it. I found this process pretty easy until I had to fit the wheels. It seemed that no matter what type of wheel unit I used, it was very hard to control the trolly. I was about to give up when I mentioned my problem to my brother. He put me in touch with a guy who is a wheel specialist. He recommended I use a particular type of castor wheel. I followed his advice and it worked great! I hope you like my blog.
